The AA12 features NAT's ICS TIE LINE, allowing it to be connected to any other NAT
audio product with the same feature, and a MUSIC input, with the music muted by TX,
RX or ICS activity.
Internal control is provided for radio receive level, artificial transmit sidetone level, music
level, and ATC mute level. Intercom level and VOX squelch are adjustable from the
front panel.
ICS operation allows transmit during any ICS mode simply by use of any TX PTT
switch.
The different models of the unit permit variations of the front panel labeling of the
inputs/outputs, and the option of either Dzus or tray mounting.
